### 1/5 — Can’t login anymore

*2024-08-22, version 2.0.2*

I installed the app, created an account and configured all the settings. The next day I couldn’t login anymore, I can’t even reset the password it’s giving an error for both action.
I tried to create a new account with a different email address not working. Uninstalled and reinstalled, same issue. Kind of useless application!

### 1/5 — Poor App Design and screen Layout

Thermostat has also lost WiFi connection. Did work before now no clear steps to resolve. Not sure if iOS or wifi upgrades caused this or both.

### 3/5 — Nice app but needs an update

Je conseil particulièrement cet apps et le thermostat flp56 pour ceux qui sont soucieux de leur confort tout en économisant
